  • ClassCaseException on GL11ExtensionPack. Rendering to texture on OpenGL android

    - by Joe
    I'm trying to render to a texture (really thought it would be easier than this!) I found this resource: which seems to be exactly what I want I'm getting a ClassCastException however, on GL11ExtensionPack gl11ep = (GL11ExtensionPack) gl; Can anyone tell me why? public void renderToTexture(GLRenderer glRenderer, GL10 gl) { boolean checkIfContextSupportsExtension = checkIfContextSupportsExtension(gl, "GL_OES_framebuffer_object"); if(checkIfContextSupportsExtension) { GL11ExtensionPack gl11ep = (GL11ExtensionPack) gl; int mFrameBuffer = createFrameBuffer(gl,texture.getWidth(), texture.getHeight(), texture.getGLID()); gl11ep.glBindFramebufferOES(GL11ExtensionPack.GL_FRAMEBUFFER_OES, mFrameBuffer); gl.glViewport(0, 0,texture.getWidth(), texture.getHeight()); gl.glLoadIdentity(); int halfWidth = texture.getWidth()/2;//width/2; int halfHeight = texture.getHeight()/2;//height/2; GLU.gluOrtho2D(gl, -halfWidth, halfWidth , -halfHeight, halfHeight); gl.glMatrixMode(GL10.GL_MODELVIEW); gl.glLoadIdentity(); gl.glEnable(GL10.GL_TEXTURE_2D); Quad quad = new Quad(texture.getWidth(), texture.getHeight()); quad.setTexture(texture); SpriteRenderable sr = new SpriteRenderable(quad); //sr.setPosition(new Interpolation<Vector2>(new Vector2(-(float)texture.getWidth()/2f,-(float)texture.getHeight()/2f))); //sr.setPosition(new Interpolation<Vector2>(new Vector2((float)(texture.getWidth()/2f),0))); //sr.setPosition(new Interpolation<Vector2>(new Vector2(200,-200))); sr.setAngle(0.05f); sr.renderTo(glRenderer, gl, 1); for (Renderable renderable : renderThese) { if (renderable.isVisible()) { renderable.renderTo(glRenderer, gl, 1); } } gl11ep.glBindFramebufferOES(GL11ExtensionPack.GL_FRAMEBUFFER_OES, 0); } }

  • How to construct LambdaExpression with conversion

    - by nerijus
    I need to sort in ajax response grid by column name. Column value is number stored as a string. Let's say some trivial class (in real-life situation there is no possibility to modify this class): class TestObject { public TestObject(string v) { this.Value = v; } public string Value { get; set; } } then simple test: [Test] public void LambdaConstructionTest() { var queryable = new List<TestObject> { new TestObject("5"), new TestObject("55"), new TestObject("90"), new TestObject("9"), new TestObject("09"), new TestObject("900"), }.AsQueryable(); var sortingColumn = "Value"; ParameterExpression parameter = Expression.Parameter(queryable.ElementType); MemberExpression property = Expression.Property(parameter, sortingColumn); //// tried this one: var c = Expression.Convert(property, typeof(double)); LambdaExpression lambda = Expression.Lambda(property, parameter); //// constructs: o=>o.Value var callExpression = Expression.Call(typeof (Double), "Parse", null, property); var methodCallExpression = Expression.Call( typeof(Queryable), "OrderBy", new[] { queryable.ElementType, property.Type }, queryable.Expression, Expression.Quote(lambda)); // works, but sorts by string values. //Expression.Quote(callExpression)); // getting: System.ArgumentException {"Quoted expression must be a lambda"} var querable = queryable.Provider.CreateQuery<TestObject>(methodCallExpression); // return querable; // <- this is the return of what I need. } Sorry for not being clear in my first post as @SLaks answer was correct but I do not know how to construct correct lambda expression in this case.

  • How do I animate UserControl objects using Storyboard and DoubleAnimation?

    - by Neo
    In my WPF application, I have a Canvas object that contains some UserControl objects. I wish to animate the UserControl objects within the Canvas using DoubleAnimation so that they go from the right of the Canvas to the left of the Canvas. This is how I have done it so far (by passing the UserControl objects into the function): private void Animate(FrameworkElement e) { DoubleAnimation ani = new DoubleAnimation() { From = _container.ActualWidth, To = 0.0, Duration = new Duration(new TimeSpan(0, 0, 10), TargetElement = e }; TranslateTransform trans = new TranslateTransform(); e.RenderTransform = trans; trans.BeginAnimation(TranslateTransform.XProperty, ani, HandoffBehavior.Compose); } However, this doesn't allow me to pause the animation, so I have considered using a Storyboard instead to do this, but I'm not sure how to implement this. This has been my attempt so far: private void Animate(FrameworkElement e) { DoubleAnimation ani = new DoubleAnimation() { From = _container.ActualWidth, To = 0.0, Duration = new Duration(new TimeSpan(0, 0, 10), TargetElement = e }; Storyboard stb = new Storyboard(); Storyboard.SetTarget(ani, e); Storyboard.SetTargetProperty(ani, "Left"); stb.Children.Add(ani); stb.Begin(); } Of course, this fails as UserControl doesn't have a Left property. How can I achieve what I'm after? Thanks.

  • Calling webservice via server causes java.net.MalformedURLException: no protocol

    - by Thomas
    I am writing a web-service, which parses an xml file. In the client, I read the whole content of the xml into a String then I give it to the web-service. If I run my web-service with main as a Java-Application (for tests) there is no problem, no error messages. However when I try to call it via the server, I get the following error: java.net.MalformedURLException: no protocol I use the same xml file, the same code (without main), and I just cannot figure out, what the cause of the error can be. here is my code: DOMParser parser=new DOMParser(); try { parser.setFeature("http://xml.org/sax/features/validation", true); parser.setFeature("http://apache.org/xml/features/validation/schema",true); parser.setFeature("http://apache.org/xml/features/validation/dynamic",true); parser.setErrorHandler(new myErrorHandler()); parser.parse(new InputSource(new StringReader(xmlFile))); document=parser.getDocument(); xmlFile is constructed in the client so: String myFile ="C:/test.xml"; File file=new File(myFile); String myString=""; FileInputStream fis=new FileInputStream(file); BufferedInputStream bis=new BufferedInputStream(fis); DataInputStream dis=new DataInputStream(bis); while (dis.available()!=0) { myString=myString+dis.readLine(); } fis.close(); bis.close(); dis.close(); Any suggestions will be appreciated!

  • Keeping the UI responsive while parsing a very large logfile

    - by Carlos
    I'm writing an app that parses a very large logfile, so that the user can see the contents in a treeview format. I've used a BackGroundWorker to read the file, and as it parses each message, I use a BeginInvoke to get the GUI thread to add a node to my treeview. Unfortunately, there's two issues: The treeview is unresponsive to clicks or scrolls while the file is being parsed. I would like users to be able to examine (ie expand) nodes while the file is parsing, so that they don't have to wait for the whole file to finish parsing. The treeview flickers each time a new node is added. Here's the code inside the form: private void btnChangeDir_Click(object sender, EventArgs e) { OpenFileDialog browser = new OpenFileDialog(); if (browser.ShowDialog() == DialogResult.OK) { tbSearchDir.Text = browser.FileName; BackgroundWorker bgw = new BackgroundWorker(); bgw.DoWork += (ob, evArgs) => ParseFile(tbSearchDir.Text); bgw.RunWorkerAsync(); } } private void ParseFile(string inputfile) { FileStream logFileStream = new FileStream(inputfile, FileMode.Open, FileAccess.Read, FileShare.ReadWrite); StreamReader LogsFile = new StreamReader(logFileStream); while (!LogsFile.EndOfStream) { string Msgtxt = LogsFile.ReadLine(); Message msg = new Message(Msgtxt.Substring(26)); //Reads the text into a class with appropriate members AddTreeViewNode(msg); } } private void AddTreeViewNode(Message msg) { TreeNode newNode = new TreeNode(msg.SeqNum); BeginInvoke(new Action(() => { treeView1.BeginUpdate(); treeView1.Nodes.Add(newNode); treeView1.EndUpdate(); Refresh(); } )); } What needs to be changed?

  • Deadlock in ThreadPoolExecutor

    - by Vitaly
    Encountered a situation when ThreadPoolExecutor is parked in execute(Runnable) function while all the ThreadPool threads are waiting in getTask func, workQueue is empty. Does anybody have any ideas? The ThreadPoolExecutor is created with ArrayBlockingQueue, corePoolSize == maximumPoolSize = 4 [Edit] To be more precise, the thread is blocked in ThreadPoolExecutor.exec(Runnable command) func. It has the task to execute, but doesn't do it. [Edit2] The executor is blocked somewhere inside the working queue (ArrayBlockingQueue).

  • Problem with persisting a collection, that references an internal property, at design time in winfor

    - by Jules
    ETA: Jesus, I'm sick of this. This problem was specifically about persisting an interface collection but now on further testing it doesn't work for a normal collection. Here's some even simpler code: Public Class Anger End Class Public Class MyButton Inherits Button Private _Annoyance As List(Of Anger) <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Annoyance() As List(Of Anger) Get Return _Annoyance End Get End Property Private _InternalAnger As Anger <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property InternalAnger() As Anger Get Return Me._InternalAnger End Get End Property Public Sub New() Me._Annoyance = New List(Of Anger) Me._InternalAnger = New Anger Me._Annoyance.Add(Me._InternalAnger) End Sub End Class The designer screws up the persistence code in the same way as the original problem. ---- Original Problem The easiest way to explain this problem is to show you some code: Public Interface IAmAnnoyed End Interface Public Class IAmAnnoyedCollection Inherits ObjectModel.Collection(Of IAmAnnoyed) End Class Public Class Anger Implements IAmAnnoyed End Class Public Class MyButton Inherits Button Private _Annoyance As IAmAnnoyedCollection <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Annoyance() As IAmAnnoyedCollection Get Return _Annoyance End Get End Property Private _InternalAnger As Anger <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property InternalAnger() As Anger Get Return Me._InternalAnger End Get End Property Public Sub New() Me._Annoyance = New IAmAnnoyedCollection Me._InternalAnger = New Anger Me._Annoyance.Add(Me._InternalAnger) End Sub End Class And this is the code that the designer generates: Private Sub InitializeComponent() Dim Anger1 As Anger = New Anger Me.MyButton1 = New MyButton ' 'MyButton1 ' Me.MyButton1.Annoyance.Add(Anger1) // Should be: Me.MyButton1.Annoyance.Add(Me.MyButton1.InternalAnger) ' 'Form1 ' Me.Controls.Add(Me.MyButton1) End Sub I've added a comment to the above to show how the code should have been generated. Now, if I dispense with the interface and just have a collection of Anger, then it persists correctly. Any ideas?

  • C# WinForms. Multiple Forms in separate threads

    - by Calum Murray
    I'm trying to run an ATM Simulation in C# with Windows Forms that can have more than one instance of an ATM machine transacting with a bank account simultaneously. The idea is to use semaphores/locking to block critical code that may lead to race conditions. My question is this: How can I run two Forms simultaneously on separate threads? In particular, how does all of this fit in with the Application.Run() that's already there? Here's my main class: public class Bank { private Account[] ac = new Account[3]; private ATM atm; public Bank() { ac[0] = new Account(300, 1111, 111111); ac[1] = new Account(750, 2222, 222222); ac[2] = new Account(3000, 3333, 333333); Application.Run(new ATM(ac)); } static void Main(string[] args) { new Bank(); } } ...that I want to run two of these forms on separate threads... public partial class ATM : Form { //local reference to the array of accounts private Account[] ac; //this is a reference to the account that is being used private Account activeAccount = null; private static int stepCount = 0; private string buffer = ""; // the ATM constructor takes an array of account objects as a reference public ATM(Account[] ac) { InitializeComponent(); //Sets up Form ATM GUI in ATM.Designer.cs this.ac = ac; } ... I've tried using Thread ATM2 = new Thread(new ThreadStart(/*What goes in here?*/)); But what method do I put in the ThreadStart constructor, since the ATM form is event-driven and there's no one method controlling it? Thanks, Calum

  • Lucene and Special Characters

    - by Brandon
    I am using Lucene.Net 2.0 to index some fields from a database table. One of the fields is a 'Name' field which allows special characters. When I perform a search, it does not find my document that contains a term with special characters. I index my field as such: Directory DALDirectory = FSDirectory.GetDirectory(@"C:\Indexes\Name", false); Analyzer analyzer = new StandardAnalyzer(); IndexWriter indexWriter = new IndexWriter(DALDirectory, analyzer, true, IndexWriter.MaxFieldLength.UNLIMITED); Document doc = new Document(); doc.Add(new Field("Name", "Test (Test)", Field.Store.YES, Field.Index.TOKENIZED)); indexWriter.AddDocument(doc); indexWriter.Optimize(); indexWriter.Close(); And I search doing the following: value = value.Trim().ToLower(); value = QueryParser.Escape(value); Query searchQuery = new TermQuery(new Term(field, value)); Searcher searcher = new IndexSearcher(DALDirectory); TopDocCollector collector = new TopDocCollector(searcher.MaxDoc()); searcher.Search(searchQuery, collector); ScoreDoc[] hits = collector.TopDocs().scoreDocs; If I perform a search for field as 'Name' and value as 'Test', it finds the document. If I perform the same search as 'Name' and value as 'Test (Test)', then it does not find the document. Even more strange, if I remove the QueryParser.Escape line do a search for a GUID (which, of course, contains hyphens) it finds documents where the GUID value matches, but performing the same search with the value as 'Test (Test)' still yields no results. I am unsure what I am doing wrong. I am using the QueryParser.Escape method to escape the special characters and am storing the field and searching by the Lucene.Net's examples. Any thoughts?

  • WCF Discovery finds endpoint but host is "localhost"

    - by Flo
    I am trying to use the Discovery feature in WCF using http://msdn.microsoft.com/en-us/library/dd456783(v=VS.100).aspx as a starting point. It works fine on my machine, but then I wanted to run the service on a different machine. The service was discovered properly but the hostname of the found service is always "localhost" which is of course not much use. Service Endpoint: var endpointAddress = new EndpointAddress(new UriBuilder { Scheme = Uri.UriSchemeNetTcp, Port = port}.Uri); var endpoint = new ServiceEndpoint(ContractDescription.GetContract(typeof(IServiceInterface)), new NetTcpBinding (), endpointAddress); Client: static EndpointAddress FindServiceAddress<T>() { Stopwatch stopwatch = new Stopwatch(); stopwatch.Start(); DiscoveryClient discoveryClient = new DiscoveryClient(new UdpDiscoveryEndpoint()); // Find endpoints FindResponse findResponse = discoveryClient.Find(new FindCriteria(typeof(T))); Console.WriteLine(string.Format("Searched for {0} seconds. Found {1} Endpoint(s).",stopwatch.ElapsedMilliseconds / 1000,findResponse.Endpoints.Count)); if (findResponse.Endpoints.Count > 0) { return findResponse.Endpoints[0].Address; } return null; } Should I simply set the Host to System.Environment.MachineName?

  • Treetop basic parsing and regular expression usage

    - by ucint
    I'm developing a script using the ruby Treetop library and having issues working with its syntax for regex's. First off, many regular expressions that work in other settings dont work the same in treetop. This is my grammar: (myline.treetop) grammar MyLine rule line string whitespace condition end rule string [\S]* end rule whitespace [\s]* end rule condition "new" / "old" / "used" end end This is my usage: (usage.rb) require 'rubygems' require 'treetop' require 'polyglot' require 'myline' parser = MyLineParser.new p parser.parse("randomstring new") This should find the word new for sure and it does! Now I wont to extend it so that it can find new if the input string becomes "randomstring anotherstring new yetanother andanother" and possibly have any number of strings followed by whitespace (tab included) before and after the regex for rule condition. In other words, if I pass it any sentence with the word "new" etc in it, it should be able to match it. So let's say I change my grammar to: rule line string whitespace condition whitespace string end Then, it should be able to find a match for: p parser.parse("randomstring new anotherstring") So, what do I have to do to allow the string whitespace to be repeated before and after condition? If I try to write this: rule line (string whitespace)* condition (whitespace string)* end , it goes in an infinite loop. If i replace the above () with [], it returns nil In general, regex's return a match when i use the above, but treetop regex's dont. Does anyone have any tips/points on how to go about this? Plus, since there isn't much documentation for treetop and the examples are either too trivial or too complex, is there anyone who knows a more thorough documentation/guide for treetop?

  • How to store a public key in a machine-level RSA key container

    - by Andrew Kimball
    I'm having a problem using a machine level RSA key container when storing only the public key of a public/private key pair. The following code creates a public/private pair and extracts the public key from that pair. The pair and the public key are stored in separate key containers. The keys are then obtained from those key containers at which point they should be the same as the keys going into the containers. The code works when CspProviderFlags.UseDefaultKeyContainer is specified for CspParameters.Flags (i.e. the key read back out from the PublicKey container is the same), but when CspProviderFlags.UseMachineKeyStore is specified for CspParameters.Flags the key read back from PublicKey is different. Why is the behaviour different, and what do I need to do differently to retrieve the public key from a machine-level RSA key container? var publicPrivateRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicPrivateKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ) { PersistKeyInCsp = true, }; var publicRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ) { PersistKeyInCsp = true }; //Export the key. publicRsa.ImportParameters(publicPrivateRsa.ExportParameters(false)); Console.WriteLine(publicRsa.ToXmlString(false)); Console.WriteLine(publicPrivateRsa.ToXmlString(false)); //Dispose those two CSPs. using (publicRsa) { publicRsa.Clear(); } using (publicPrivateRsa) { publicRsa.Clear(); } publicPrivateRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicPrivateKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ); publicRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ); Console.WriteLine(publicRsa.ToXmlString(false)); Console.WriteLine(publicPrivateRsa.ToXmlString(false)); using (publicRsa) { publicRsa.Clear(); } using (publicPrivateRsa) { publicRsa.Clear(); }

  • Saving multiple objects in a single call in rails

    - by CaptnCraig
    I have a method in rails that is doing something like this: a = Foo.new("bar") a.save b = Foo.new("baz") b.save ... x = Foo.new("123", :parent_id => a.id) x.save ... z = Foo.new("zxy", :parent_id => b.id) z.save The problem is this takes longer and longer the more entities I add. I suspect this is because it has to hit the database for every record. Since they are nested, I know I can't save the children before the parents are saved, but I would like to save all of the parents at once, and then all of the children. It would be nice to do something like: a = Foo.new("bar") b = Foo.new("baz") ... saveall(a,b,...) x = Foo.new("123", :parent_id => a.id) ... z = Foo.new("zxy", :parent_id => b.id) saveall(x,...,z) That would do it all in only two database hits. Is there an easy way to do this in rails, or am I stuck doing it one at a time?

  • How do I write test code to exercise a C# generic Pair<TKey, TValue> ?

    - by Scott Davies
    Hi, I am reading through Jon Skeet's "C# in Depth", first edition (which is a great book). I'm in section 3.3.3, page 84, "Implementing Generics". Generics always confuse me, so I wrote some code to exercise the sample. The code provided is: using System; using System.Collections.Generic; public sealed class Pair<TFirst, TSecond> : IEquatable<Pair<TFirst, TSecond>> { private readonly TFirst first; private readonly TSecond second; public Pair(TFirst first, TSecond second) { this.first = first; this.second = second; } ...property getters... public bool Equals(Pair<TFirst, TSecond> other) { if (other == null) { return false; } return EqualityComparer<TFirst>.Default.Equals(this.First, other.First) && EqualityComparer<TSecond>.Default.Equals(this.Second, other.Second); } My code is: class MyClass { public static void Main (string[] args) { // Create new pair. Pair thePair = new Pair(new String("1"), new String("1")); // Compare a new pair to previous pair by generating a second pair. if (thePair.Equals(new Pair(new string("1"), new string("1")))) System.Console.WriteLine("Equal"); else System.Console.WriteLine("Not equal"); } } The compiler complains: "Using the generic type 'ManningListing36.Paie' requires 2 type argument(s) CS0305" What am I doing wrong ? Thanks, Scott

  • WCF JSON Service returns XML on Fault

    - by Anthony Johnston
    I am running a ServiceHost to test one of my services and all works fine until I throw a FaultException - bang I get XML not JSON my service contract - lovely /// <summary> /// <para>Get category by id</para> /// </summary> [OperationContract(AsyncPattern = true)] [FaultContract(typeof(CategoryNotFound))] [FaultContract(typeof(UnexpectedExceptionDetail))] IAsyncResult BeginCategoryById( CategoryByIdRequest request, AsyncCallback callback, object state); CategoryByIdResponse EndCategoryById(IAsyncResult result); Host Set-up - scrummy yum var host = new ServiceHost(serviceType, new Uri(serviceUrl)); host.AddServiceEndpoint( serviceContract, new WebHttpBinding(), "") .Behaviors.Add( new WebHttpBehavior { DefaultBodyStyle = WebMessageBodyStyle.Bare, DefaultOutgoingResponseFormat = WebMessageFormat.Json, FaultExceptionEnabled = true }); host.Open(); Here's the call - oo belly ache var request = WebRequest.Create(serviceUrl + "/" + serviceName); request.Method = "POST"; request.ContentType = "application/json; charset=utf-8"; request.ContentLength = 0; try { // receive response using (var response = request.GetResponse()) { var responseStream = response.GetResponseStream(); // convert back into referenced object for verification var deserialiser = new DataContractJsonSerializer(typeof (TResponseData)); return (TResponseData) deserialiser.ReadObject(responseStream); } } catch (WebException wex) { var response = wex.Response; using (var responseStream = response.GetResponseStream()) { // convert back into fault //var deserialiser = new DataContractJsonSerializer(typeof(FaultException<CategoryNotFound>)); //var fex = (FaultException<CategoryNotFound>)deserialiser.ReadObject(responseStream); var text = new StreamReader(responseStream).ReadToEnd(); var fex = new Exception(text, wex); Logger.Error(fex); throw fex; } } the text var contains the correct fault, but serialized as Xml What have I done wrong here?

  • Overlay SVG diagrams on google maps

    - by ThibThib
    Hello I would like to add an overlay image on a google map. This image is a SVG file I have generated (python with svgfig). I am using the following code if (GBrowserIsCompatible()) { var map = new GMap2(document.getElementById("map_canvas")); map.setCenter(new GLatLng(48.8, 2.4), 12);     // ground overlay     var boundaries = new GLatLngBounds(new GLatLng(48.283188032632829, 1.9675270369830129), new GLatLng(49.187215000000002, 2.7771877478303999));     var oldmap = new GGroundOverlay("test.svg", boundaries); map.addControl(new GSmallMapControl()); map.addControl(new GMapTypeControl()); map.addOverlay(oldmap); } Surprisingly, it works with Safari 4, but it doesn't with Firefox (with Safari 3, the background is not transparent) Does anyone has an idea on how I could overlay a SVG ? Thanks PS1: I read some works like this or the source code of swa.ethz.ch/googlemaps, but it seems that they have to use javascript code to parse the SVG and add one by one all the elements (but I did not understood all the source...) PS2: The SVG is composed of different filled paths and circles, with transparency. If there is no solution to overlay my SVG, I can use 2 alternative solutions: rasterize the SVG convert the paths and circles in GPolygons But, I do not really like the 1st solution because of the poor quality of the bitmap and the time to generate it with antialiasing. And for the 2nd solutions, the arcs, ellipses and circles will have to be decomposed into small polylines. A lot of them will be necessary for a good result. But I have around 3000 arcs and circles to draw, so...

  • Link doesnt work in FF

    - by venom
    Here is the link: <a href="javascript://" onClick="print_gonder();"><img src="/images/print.gif" title="Gönder" border="0"></a> and its function print_gonder: function print_gonder() { var satirsayisi=document.list_basketww.row_count.value; var amnt=new Array(satirsayisi); var prc=new Array(satirsayisi); var kdv=new Array(satirsayisi); var kon=new Array(satirsayisi); var yap=new Array(satirsayisi); var ona=new Array(satirsayisi); var ode=new Array(satirsayisi); var tes=new Array(satirsayisi); for (i=0; i<satirsayisi; i++) { amnt[i]=eval("document.getElementById('amount" + (i+1) + "')").value; prc[i]=filterNum(eval("document.getElementById('price" + (i+1) + "')").value); kdv[i]=eval("document.getElementById('tax_dif" + (i+1) + "')").value; kon=eval("document.getElementById('konu')").value; yap=eval("document.getElementById('yapan')").value; ona=eval("document.getElementById('onay')").value; ode=eval("document.getElementById('odeme')").value; tes=eval("document.getElementById('teslim')").value; } windowopen('<cfoutput>#request.self#?fuseaction=objects2.popup_sale_propose&print=true#page_code#&amnt='+amnt+'&prc='+prc+'&kdv='+kdv+'&konu='+kon+'&yapan='+yap+'&onay='+ona+'&odeme='+ode+'&teslim='+tes+'</cfoutput>','page'); } The problem is that this link doesnt work in FF but work in IE, but if i change the function into something like this: <a href="javascript://" onClick="<cfoutput>windowopen('#request.self#?fuseaction=objects2.popup_sale_propose&print=true#page_code#','page')</cfoutput"><img src="/images/print.gif" title="Gönder" border="0"></a> it perfectly works in all the browsers.. i think that the problem is in defining the values of the functions, the FF just doesnt understand them... btw, the system is Workcube and it uses the Cold Fusion.

  • Bulk Insert of hundreds of millions of records

    - by Dave Jarvis
    What is the fastest way to insert 237 million records into a table that has rules (for distributing the data across 84 child tables)? First I tried inserts. No go. Then I tried inserts with BEGIN/COMMIT. Not nearly fast enough. Next, I tried COPY FROM, but then noticed the documentation states that the rules are ignored. (And it was having difficulties with the column order and date format -- it said that '1984-07-1' was not a valid integer; true, but a bit unexpected.) Some example data: station_id,taken,amount,category_id,flag 1,'1984-07-1',0,4, 1,'1984-07-2',0,4, 1,'1984-07-3',0,4, 1,'1984-07-4',0,4,T Here is the table structure (with one rule included): CREATE TABLE climate.measurement ( id bigserial NOT NULL, station_id integer NOT NULL, taken date NOT NULL, amount numeric(8,2) NOT NULL, category_id smallint NOT NULL, flag character varying(1) NOT NULL DEFAULT ' '::character varying ) WITH ( OIDS=FALSE ); ALTER TABLE climate.measurement OWNER TO postgres; CREATE OR REPLACE RULE i_measurement_01_001 AS ON INSERT TO climate.measurement WHERE date_part('month'::text, new.taken)::integer = 1 AND new.category_id = 1 DO INSTEAD INSERT INTO climate.measurement_01_001 (id, station_id, taken, amount, category_id, flag) VALUES (new.id, new.station_id, new.taken, new.amount, new.category_id, new.flag); I can generate the data into any format. Am looking for something that won't take four days. I originally had the data in MySQL (still do), but am hoping to get a performance increase by switching to PostgreSQL and am eager to use its PL/R extensions for stats. I was also thinking about using: http://pgbulkload.projects.postgresql.org/ Any help, tips, or guidance would be greatly appreciated. Thank you!

  • Best practice for writing ARRAYS

    - by Douglas
    I've got an array with about 250 entries in it, each their own array of values. Each entry is a point on a map, and each array holds info for: name, another array for points this point can connect to, latitude, longitude, short for of name, a boolean, and another boolean The array has been written by another developer in my team, and he has written it as such: names[0]=new Array; names[0][0]="Campus Ice Centre"; names[0][1]= new Array(0,1,2); names[0][2]=43.95081811364498; names[0][3]=-78.89848709106445; names[0][4]="CIC"; names[0][5]=false; names[0][6]=false; names[1]=new Array; names[1][0]="Shagwell's"; names[1][1]= new Array(0,1); names[1][2]=43.95090307839151; names[1][3]=-78.89815986156464; names[1][4]="shg"; names[1][5]=false; names[1][6]=false; Where I would probably have personally written it like this: var names = [] names[0] = new Array("Campus Ice Centre", new Array[0,1,2], 43.95081811364498, -78.89848709106445, "CIC", false, false); names[1] = new Array("Shagwell's", new Array[0,1], 43.95090307839151, -78.89815986156464, 'shg", false, false); They both work perfectly fine of course, but what I'm wondering is: 1) does one take longer than the other to actually process? 2) am I incorrect in assuming there is a benefit to the compactness of my version of the same thing? I'm just a little worried about his 3000 lines of code versus my 3-400 to get the same result. Thanks in advance for any guidance.

  • Google Maps API V3: How to jump to a specific marker from outside the map?

    - by Tom
    I have a map with two markers on it. The initial view of the map only shows one marker, and I want to provide a link next to the map that will move the map to the 2nd marker when clicked. Here's a demo of what I want, using v2 of the API: http://arts.brighton.ac.uk/contact-university-of-brighton-faculty-of-arts (note the links below the map) Here's what I have so far: <script type="text/javascript"> function initialize() { var latlng = new google.maps.LatLng(50.823817, -0.135634); var myOptions = { zoom: 13, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP, mapTypeControlOptions: { style: google.maps.MapTypeControlStyle.DROPDOWN_MENU } , scaleControl: false }; var map = new google.maps.Map(document.getElementById("map"), myOptions); // 1st marker var marker1 = new google.maps.Marker({ position: new google.maps.LatLng(50.823817, -0.135634), map: map, title: 'my title' }); var infowindow = new google.maps.InfoWindow({ content: 'my window content' }); google.maps.event.addListener(marker1, 'click', function() { infowindow.open(map, marker1); }); // 2nd marker var marker2 = new google.maps.Marker({ position: new google.maps.LatLng(51.5262405, -0.074549), map: map, title: 'my 2nd title'}); var infowindow2 = new google.maps.InfoWindow({ content: 'content for my 2nd window' }); google.maps.event.addListener(marker2, 'click', function() { infowindow2.open(map, marker2); }); } </script> So what I'd like to add is a link to marker2, to move the map some 50-odd miles up, e.g. <a href="#marker2">Second location</a>. How would I do this?
